STAPLE-SET.

Specification of Letters Patent.

Patented Jan. 23, 1917.

Application filed May 19, 1916. Serial No. 98,650.

To all whom it may concern Be it known that I, EDWARD P. CHAPMAN, acitizen of the United States, residing at Findlay, in the county ofShelby, State of Illinois, have invented certain new and usefulImprovements in Staple-Sets; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to a staple set.

It is well known that when an attempt is made to'drive a staple into apiece of hard wood such as a fence post or the like that the legs of thestaple often spread so that it becomes necessary to remove the stapleand replace it by another. Now this spreading of the legs occurs notonly upon the initial movement of. the staple into the wood but alsooccurs up to the time when the staple is' finally in place.

It is therefore an object of the invention to provide a device by meansof which staples may be set in such manner that the possibility of thelegs spreading at any time during the setting operation is entirelyobviated.

A further object of the invention resides in the provision of a deviceof this character which will be cheap to manufacture and easilyoperated.

with these and other objects in view, such as will appear as mydescription progresses, my invention comprises the combination andarrangement of parts as set forth in and falling within the scope of theappended claim.

In the drawing: Figure 1 is a perspective view of a device constructedin accordance with the invention; Fig. 2 is a longitudinal sectionalview, and Fig. 3 is a transverse sectional view on line 3-3 of Fig. 2.

The embodiment of the invention illustrated in the drawing includes abody portion 1 which is tapered from end to end so that the end 2 whichreceives the force for driving the staple is smaller than the oppositeor socket end. Formed in this opposite end of the body portion 1 are aplurality of sockets 3, 4. and 5. These sockets are of such shapes thatthey will receive the staple and permit the'legs thereof to extend out--wood until the adjacent end wardly from the set. The socket 5 isconsiderably deeper than the sockets 3 and 4 while the socket 4 isdeeper than the socket 3 as will be readily observed from an inspectionof Fig. 2 of the drawing. made of gradually decreasing depths So as toaccommodate the staple at various stages of its entrance into the woodin which it is being set.

In using the device the staple is first inserted in the socket 5 anddriven into the of the body portion of the device contacts with thewood. The staple is then disengaged from this socket and engaged withthe next succeeding socket 4c and driven farther into the wood in asimilar manner and is finally set in place by the device when it isengaged in the last socket therein. 4

It is of course to be understood that the number of sockets may beincreased as desired, the essential requirement being that there be aplurality of sockets for guiding the legs of the staple during theentire setting operation.

While I have illustrated and described a particular embodiment of myinvention, it has merely been for the sake of convenience and I do notwish to be limited to that particular embodiment as it is obvious thatnumerous changes may be made in the details of construction withoutdeparting from the spirit of the invention or exceeding the scope of theappended claim.

That I claim is A staple set comprising a body portion having a seriesof independent staple receiving sockets in one end thereof, whichsockets have contours similar to that of a wire staple and are ofgradually decreasing depths whereby a staple may be engaged in thedeepest of the sockets during the initial movement of the staple intoits set position and subsequently engaged in the remaining sockets,successively, in the order of their decrease in its further movementinto its set position. 7

In testimony whereof I aflix my signature in the presence of twowitnesses.
